It should be there.. hmm.. did you try it at night maybe? Could be a bug but I dont see how this won't work though
I tried it day and night, before/after concert, several days, if something triggers the phenomenon, but it didn't. Maybe the problem was that I started the game in browser, exported the savings and played after on windows application. Never mind, I really like the game, thank you for the opportunity to play with it and look forward to further improvements!
